PENCIL-TIP.

Specification of Letters Patent.- P t nt d Nov, 28, 1911.

Application filed May 4, 1310. Serial No. 559,253. 7

To all whom it may concern:

Be it known that I, JOSEPH V. ROBERT- soN, a citizen of the United States, residing at Cadiz, in the county of Harrison and State ofOhio, have invented certain new and useful Improvements in Pencil-Tips, of which the following is a specification.

My invention has relation to new and useful improvements in pencil tips and more may be applied to a new pencil when de- I sired. V

A further object is to provide a receiving socket for the tape measure casing which is in the form of a resilient clasp so as to positively retain the casing in position but allow of the ready removal thereof when desired.

Other objects and advantages will be apparent from the following description, and it will be understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.

In the drawings: Figure 1 is a side elevation of my improved device, Fig. 2 is a longitudinal axial sectional view on the line 22 of Fig. l and showing the pencil in a reversed position, Fig. 3 is a detail sectional view of the tip taken at right angles to Fig. 2 and longitudinally of the axis of the pencil, Fig. 4 is a detail longitudinal axial sectional view of a modifiedarrangement, Fig. 5 is a sectional view on the line 5--5 of Fig. 4, the drum being removed.

In the drawings, A indicates the tip which is preferably formed of sheet metal the upper portion 10 being adapted to contain an erasing rubber 11, while the lower end of the tip comprises a pencil receiving socket 12 which is provided with longitudinal slots 13 upon diametrically opposite sides thereof and extending throughout the length of the portion 12 so as to permit the pencil or the 7 like to be forced thereinto and tightly held.

The tip intermediate of the upper or rubber receiving. socket 10 and the lower or pencil receiving socket 12 .is enlarged to form two side strips or resilient arms 14, said strips having grooves extended longitudinally of their inner faces and provided with a central enlargement 15 on one side while the opposite strip is provided with an opening 16 extending therethrough for a purpose to be presently described.

Disposed within the slotted opening formed by the strips and adapted to be resiliently clasped therebetween is a tape measure casing 17 of suitable diameter, said measure being of the locking spindle type, and having a projection 18 centrally of one side and adapted to be seated within the cen- -tral enlargement 15 of one ofthe strips, the

opposite side of the casing having a spindle 19 projecting therefrom and disposed within the opening 16, so as to properly hold the casing in position. Between the inner end of the spindle and the enlargement 18 isa coil spring 18' whichholds said spindle normally outward. The tape measure casing as described, is provided with the spring pressed spindle l9 and may be constructed in theusual'manner as ordinary tape measures of this type wherein the end of the spindle thereof is partially tapered to limit it in its outward movement, which would prevent the same from passing out through the opening 16. It is also to be understood that the grooves in thest rips are adapted for guiding the projection and spindle into the enlargement and the opening respectively, when the casing is disposed therebetween, it being obvious that when the tape measure casing is inserted between the side strips 14 which are of a resilient nature, the spindle and projection will engage with the grooves in the strips so as to guide the proj ection and spindle into the enlargement and opening respectively and also prevent the casing from springing therethrough.

As shown in Fig. 2 of the drawings, the pencil when not in use is adapted to be disposed within the socket 12, lead end first, and in such position it will be properly protected from breaking and by such construction it will be readily seen that the tip member may be applied to pencils. in general without the necessity of renewing the tip.

Referring to Figs. 4 and 5 of the drawings I have illustrated a slight modification, in

which the rubber receiving socket 20 is of the usual construction and adapted to contain a rubber 21, said socket member being preferably provided with circular ribs adapted to rigidly hold the rubber.- Depending from diametrically opposite 'portions of the receiving socket member 20 are the ribs 22 which connect the said socket member 20 with the lower cylindrical member providing the socket 23 for engaging the pencil.

- The strips 22 are slightly bossed outward to accommodate the tape measure casing, while below said casing is a cylindrical portion providing the socket 23 to receive the pencil 5, the sides of said cylindrical memher being split by a longitudinally extending slot in the same manner that the portion 12 of the first described form of my invention is split. Said cylindrical member is bossed outward near the upper portion, thereof to provide the peripheral rib 24, while fitting over the cylindrical member to clamp the same against the pencil is the sleeve 25 having an outwardly bossed portion 26 providing a peripheral groove interiorly thereof to receive the rib 24 of the cylindrical member. It is to be understood that in this form, the casing is disposedbe- 1 tween the strips before the application of the sleeve 25 and the enlargement 18 and spindle 19 are guided into the grooves of the strips 22- by engagement in the slots 27 and thence into the central enlargement 15 and opening 16 respectively.

It will thus be seen that the invention is well adapted for use where a tape measure is desired andfespecially for merchants whose business would be greatly facilitated by the use of such a combination article,

which by reason of its extreme simplicity could be manufactured very cheaply.

What is claimed is An attachment for pencils consisting of tubular portions, a pair of parallel strips formed integrally with said tubesand connecting them, one of said strips having a longitudinally formed groove on its inner face and an opening formed centrally in the bottom of said groove, the other of said strips having a longitudinally formed groove and a centrally formed depression on its inner face, a cylinder casing disposed between said strips, a smaller cylindrical casing disposed concentrically within the first named casing, a tubular shaft extending transversely through the centers of both casings, the smaller of said casings having a spring therein wound on said shaft, a tape line wound on the smaller casi11g, said larger casing having an opening through which the free end of the tape extends, said larger casing having on one side and centrally arranged an enlargement for engagement in the depression of said second named strip and a spring pressed pin in said hollow shaft, said pin projecting through one side of said larger casing whereby the pin is adapted to move in said grooves of said stripsfor the insertion or removal of said casing and to casing to revolve.

In testimony whereof I aflix my signature, in p'resenge of two witnesses.
